Hi, i am having difficulties making my views to switch. Here is my code: Here is my hierarchy of presenters: AppPresenter, that contains HeaderPresenter and BodyPresenter:
public class AppPresenter extends
WidgetContainerPresenter<AppPresenter.Display> {
public interface Display extends WidgetContainerDisplay {
}
@Inject
public AppPresenter(Display display, EventBus bus,HeaderPresenter
header, BodyPresenter body) {
super(display,bus, header, body);
}
}
HeaderPresenter and BodyPresenter will never be changed.
public class BodyPresenter extends
WidgetContainerPresenter<BodyPresenter.Display> {
public interface Display extends WidgetContainerDisplay {
}
@Inject
public BodyPresenter(Display display, EventBus eventBus,
LeftMenuPresenter menu, ContentPresenter content) {
super(display, eventBus, menu, content);
}
}
BodyPresenter contains LeftMenuPresenter and ContentPresenter
And ContentPresenter must switch different presenters in it when something
is picked from the left menu(or some buttons in the header are clicked).
public class ContentPresenter extends
WidgetContainerPresenter<ContentPresenter.Display> {
public interface Display extends WidgetContainerDisplay {
}
private MyDefaultPresenter dPresenter;
@Inject
public ContentPresenter(Display display, EventBus eventBus,
MyDefaultPresenter dPresenter) {
super(display, eventBus, dPresenter);
this.dPresenter =dPresenter;
}
@Override
protected void onBind() {
super.onBind();
registerHandler(eventBus.addHandler(PresenterChangedEvent.getType(),
new PresenterChangedHandler() {
@Override
public void onPresenterChanged(PresenterChangedEvent event) {
Debugger.log("receive PresenterChangedEvent");
ContentPresenter.this.setCurrentPresenter((WidgetPresenter<?>)
event.getPresenter());
}
}));
}
}
The PresenterChangedEvent is fired onClick event from the menu or header
links/buttons, but nothing happens.
And i had to pass my other presenters in the Header or LeftMenuPresenter,
which is not quite right, they should all be passed to the ContentPresenter
and somehow swich on event.
Any ideas?
Regards.
